Abstract
Polyantimonic acid based membranes have been evaluated as a separator in alkaline water electrolysis. Therefore, thin sheets of polyantimonic acid-polysulfone in different weight ratios have been prepared using a film casting technique. Measurements of the ionic conduction of these films in alkaline medium were performed and the results of these measurements show a large scattering. In contrast to these results for polysulfone sheets, the membrane resistance data for 80 wt % polyantimonic acid-20 wt % polysulfone membranes show a very good reproducibility. Since the thickness of these membranes equals 0. 04 cm the membrane resistance at room temperature is about a factor of 2-3 higher than that of the free electrolyte.
